Asiaticoside-D (AD) was shown to efficacy of ganglionic degenerated as a pioneering observation in our earlier research. Though, extract molecular mechanisms of AD for degenerative diseases (DDs) remains largely unknown. We investigated the neuroprotective effects of AD against ROT in cerebral ganglions (CGs) of degenerative . Worms were exposed to 0.4 ppm ROT for 7 days were subjected to co- treatment with 15 ppm of AD. After, CGs was removed. The levels oxidant, non-antioxidant, antioxidant status, ganglioside, ceramide and ceramide glycanase (CGase) were estimated. The levels of (s-9 p70 and by semi-qRT- PCR. The expression pattern of tyramine beta hydroxylase (TBH), glutamate receptor (iGluR), serotonin transporter (SERT), dopamine transporters (DAT), nerve growth factors (NGF), cytochrome C oxidase (COC), NADH dehydogenase subunit-1 (ND-1), neurotrophin receptor p75 (p75NTR), neuronal nitric oxiside synthase (nNOs) interleukin 1- beta (IL1-β) and tumor necrosis factor alpha (TNF-α) by western blotting. Glutaminergic, serotogenic and dopaminergic toxicity variations were also performed. The levels of oxidant, non-antioxidant, antioxidant status, lipids, proteins and were significantly altered ( < 0.001) on ROT-induced (group II) and their levels were significantly changes ( < 0.05) by ROT+AD in CGs. The sensitive study plan concluded the neuroprotective effects of AD against ROT induced degeneration in worms and suggest that the AD deserves future studies for its use as an effective alternative medicine that could minimize the morbidity of ganglionic degenerative diseases patients.
在我们早期的研究中,积雪草苷-D(AD)对神经节退变的疗效被视为一项开创性的观察结果。然而,AD对退行性疾病(DDs)的分子作用机制在很大程度上仍不清楚。我们研究了AD对退行性脑神经元(CGs)中鱼藤酮(ROT)的神经保护作用。将蠕虫暴露于0.4 ppm的ROT中7天,然后与15 ppm的AD共同处理。之后,取出CGs。评估氧化剂、非抗氧化剂、抗氧化状态、神经节苷脂、神经酰胺和神经酰胺聚糖酶(CGase)的水平。通过半定量逆转录聚合酶链反应(semi-qRT-PCR)检测(s-9 p70和 )的水平。通过蛋白质印迹法检测酪胺β羟化酶(TBH)、谷氨酸受体(iGluR)、5-羟色胺转运体(SERT)、多巴胺转运体(DAT)、神经生长因子(NGF)、细胞色素C氧化酶(COC)、烟酰胺腺嘌呤二核苷酸脱氢酶亚基-1(ND-1)、神经营养因子受体p75(p75NTR)、神经元型一氧化氮合酶(nNOs)、白细胞介素1-β(IL1-β)和肿瘤坏死因子α(TNF-α)的表达模式。还进行了谷氨酸能、5-羟色胺能和多巴胺能毒性变化的检测。在CGs中,ROT诱导组(II组)的氧化剂、非抗氧化剂、抗氧化状态、脂质、蛋白质和 的水平显著改变(P < 0.001),而ROT + AD处理使其水平发生显著变化(P < 0.05)。敏感性研究计划得出结论,AD对ROT诱导的蠕虫退变具有神经保护作用,并表明AD作为一种有效的替代药物,有望减少神经节退行性疾病患者的发病率,值得进一步研究。
